Recent experimental results are beginning to limit seriously the theories that can be considered to explain high-temperature superconductivity. The unmistakable observations of a Fermi surface, by several groups and methods, make it the focus of realistic theories of the metallic phases. Data from angle-resolved photoemission, positron annihilaton, and de Haas-van Alphen experiments are in agreement with band theory predictions, implying that the metallic phases cannot be pictured as doped insulators. The character of the low energy excitations ("quasiparticles"), which interact strongly with atomic motions, with magnetic fluctuations, and possibly with charge fluctuations, must be sorted out before the superconducting pairing mechanism can be given a microscopic basis.
最近的实验结果开始严重限制了可以用来解释高温超导性的理论。几个研究小组和方法对费米面的明确观测，使得它成为金属相实际理论的焦点。角分辨光发射、正电子湮没和德哈斯-范阿尔芬实验的数据与能带理论的预测一致，这意味着金属相不能被描绘为掺杂的绝缘体。在给出超导配对机制的微观基础之前，必须理清与原子运动、磁涨落以及可能与电荷涨落强烈相互作用的低能激发（“准粒子”）的特性。
